Korniche's innovative range of roof lanterns, have each been designed to offer you streamlined modernity with high-performance design. This grey-framed unit comes in a range of sizes and is fitted with clear glass to bring you a U-value of 1.2 W/m2K, a light transmission of 78%, and a solar heat reflection of 42%. Engineered with thermally broken beams for optimum thermal efficiency, each roof lantern in the range has been developed to bring you maximum light and a room temperature that's comfortable whatever the weather. High-quality seals and gaskets keep even the most inclement weather at bay, and innovative tamper-proof fastenings provide you with that much-needed peace of mind when it comes to your home's security. Built with super-narrow 57mm-wide spas and ridge sections and sculpted bosses, Korniche roof lanterns offer all the traditional aesthetic appeal of timber construction but with the contemporary benefits of full, lightweight aluminium construction. But lightweight doesn't mean less strength: Korniche roof lanterns are the strongest in their class with the 6m by 4m roof lantern comfortably bearing weights of more than eight tonnes.
